摘　　要：结合面板堆石坝的施工特点,选取不同特性的筑坝材料进行现场碾压试验。通过试验成果,分析了该类筑坝材料的颗粒级配、渗透系数以及干密度等技术参数是否能够满足设计要求并选取合理、经济的碾压参数进行面板堆石坝填筑施工。Combined with concrete faced rockfill dam characteristics,field roller compaction test is conducted by selecting construction materials with various properties. Grain gradation,permeability coefficient and dry density of the construction materials are analyzed based on test results to identify whether these technical parameters meet design requirements. Thus proper and economic roller compaction parameters are selected for concrete faced rockfill dam placement construction.
